UPDATE: The MRI revealed “mild left elbow inflammation,” according to MLB.com beat writer Bryan Hoch. Pettitte will be evaluated daily and could be forced to miss his next scheduled start. A short stay on the 15-day disabled list is also a possibility.

We likely won’t know anything about his status until tomorrow. Sergio Mitre came in to relieve him today. You’d have to figure that he’d be the guy to take over Pettitte’s spot in the rotation should he have to miss any time.

Blash, 28, was acquired by the Yankees from the Padres back in December in the Chase Headley trade. In trading Blash to the Angels, the Yankees were able to free up a spot on the 40-man roster for Brandon Drury, the infielder they acquired as part of a three-team trade with the Diamondbacks and Rays on Tuesday.

Over parts of two seasons in the majors, Blash has hit an underwhelming .200/.323/.336 in 279 plate appearances. He will try to play his way into a bench role for the Angels this spring.
